This test method is intended to be used to determine the amount of water required to prepare hydraulic cement pastes with normal consistency, as required for certain standard tests.

1. Scope

1.1 This test method covers the determination of the normal consistency of hydraulic cement.

1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 1.4 for a specific warning statement.

1.4 Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. The use of gloves, protective clothing, and eye protection is recommended. Wash contact area with copious amounts of water after contact. Wash eyes for a minimum of 15 min. Avoid exposure of the body to clothing saturated with the liquid phase of the unhardened material. Remove contaminated clothing immediately after exposure.

The FerroCheck 2000 Series of portable magnetometers from Spectro Scientific quickly and conveniently measures total ferrous wear particulates in lubricating fluids. The FerroCheck 2000 unit, which measures ferrous wear particles in oils, is now joined by the FerroCheck 2100 version that adds the capability to quantify up to 15% ferrous debris in grease. The instruments enable users in both field and laboratory settings to accurately gauge evidence of ferrous wear and use the data to support condition-based...

HDXRF® technology is fast, precise, and easy to use. In addition, the technology offers a 1-mm analysis area that provides the ability to test small features for the presence of potentially toxic heavy metals, including lead. When it comes to analyzing glass materials for lead, HDXRF can offer many advantages over ICP methods. In 2013, the CPSC expanded upon its approval of HDXRF ASTM method F2853 for the quantification of lead in surface coatings to include quantification of lead in homogeneous substrates as...
